Respuesta :
Zn + H₂SO₄ = ZnSO₄ + H₂
Zn⁰ - 2e⁻ = Zn²⁺ zinc is the reducing agent
2H⁺ + 2e⁻ = H₂ hydrogen ions is oxidizer
Zn⁰ - 2e⁻ = Zn²⁺ zinc is the reducing agent
2H⁺ + 2e⁻ = H₂ hydrogen ions is oxidizer
The answer is d)
Zn has oxidation number 0; Zn(2+) has oxidation number +2. Here 2 electrons were taken away, so the Zn was oxidized. So, the transformation requires an oxidizing agent.
